My Personal Experience
The first time I made these muffins, I was running late and needed something quick for breakfast that I could eat while replying to emails. I threw together my favorite Denver omelet ingredients, poured the mixture into a muffin tin, and hoped for the best. Twenty minutes later—perfection! They were golden, fluffy, cheesy, and packed with flavor. I now keep a batch ready in the fridge most weeks and genuinely look forward to breakfast again.
Required Equipment
🧁 Muffin Tin
A standard 12-cup muffin tin is ideal to portion and bake your egg muffins evenly.
🥣 Mixing Bowl
You’ll need a medium-to-large mixing bowl to combine your egg mixture and veggies smoothly.
🧂Whisk or Fork
For beating the eggs into a nice, uniform texture.
🥄 Ladle or Measuring Cup
Helps in pouring the mixture into muffin cups neatly without spilling.
🔪 Cutting Board & Knife
To finely dice your ham, bell peppers, and onions. A sharp knife makes prep easier and quicker.
🧴Cooking Spray or Silicone Liners
Essential to prevent sticking and ensure clean, easy removal of your egg muffins.
Ingredients & Substitutions
- 8 large eggs – These are the base and provide protein and fluffiness.
- ½ cup heavy cream – Adds richness and helps keep the muffins moist.
- 1 cup diced cooked ham – Traditional to the Denver omelet. You can substitute with cooked bacon or turkey.
- ½ cup green bell pepper (finely diced) – Brings color and a mild sweetness. Red or yellow peppers work too.
- ¼ cup finely chopped onions – Adds depth of flavor. You can use scallions or skip them for a milder taste.
- 1 cup shredded cheddar cheese – Melts beautifully. Feel free to sub with mozzarella, pepper jack, or any favorite cheese.
- ½ tsp salt & ¼ tsp black pepper – Season to taste.
Optional: Add a pinch of smoked paprika or garlic powder for extra flavor.
How to Make Keto Denver Omelet Egg Muffins
- Preheat your oven to 375°F (190°C) and grease your muffin tin with cooking spray or use silicone liners.
- Crack the eggs into a large bowl, add heavy cream, salt, and pepper. Whisk until fully combined and slightly frothy.
- Add the fillings – Stir in the diced ham, bell peppers, onions, and shredded cheese.
- Distribute the mixture evenly between 12 muffin cups, filling each about ¾ full.
- Bake for 20–25 minutes or until the tops are puffed and slightly golden. A toothpick inserted should come out clean.

Frequently Asked Questions
Can I make these without dairy?
Yes! Skip the cream and cheese and add a splash of almond milk. They won’t be as creamy but still delicious.
Do they puff up a lot?
Yes, slightly. They’ll rise in the oven and settle a bit once cooled.
Can I use egg whites only?
You can, but the muffins won’t be as rich or filling. Consider adding an extra egg white or two for structure.
